Slave CPU Synchronization
6.6.1
Overview
Slave CPU synchronization is used for configurations with master and slave MP3000 Control-
lers that have CPU Units/CPU Modules with a built-in SVC Function Module in order to syn-
chronize the high-speed scan cycles of the master and slave MP3000 Controllers.
When multiple MP3000 Controllers are connected as slaves, the high-speed scans in all of the
MP3000 Controllers connected as slaves will be synchronized. The references sent from the
application program in the master will be transmitted to all of the MP3000 Controllers con-
nected as slaves at the same time. If you mount Option Modules in the slaves MP3000 Control-
lers, you can synchronize the operation of the axes connected to the Option Modules.
With slave CPU synchronization, you can distribute the application programming in the
MP3000 Controllers to distribute the application loads on the CPUs and expand memory.
The following figure shows a system configuration example.

A delay will occur in MECHATROLINK-III communications until the references from the applica-
tion program in the master reach the slaves. Therefore, the operation of the SERVOPACKs con-
nected to the master will not be synchronized with the operation of the SERVOPACKs connected
to the slaves.
